IM PROVE M ENT IN PLOW-POINTS.

Specification forming part of Letters Patent No. 68.755, dated September 10, 1867.

To all whom it may concern:

Be it known that I, HINRICK KNIPHALs; of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Plows; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyingdrawings, making part of this specification, and to the letters of refence marked thereon, like-letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention I will proceed to describe it.

This invention relates to an improved mode of protecting plows from being rendered use less by wear or injury at the point while the other parts are sound and good.

It consists in the application of a hollow removable iron or steel point to any plow from which the point becomes worn off and blunted, and also as a protecting cap when the plow is found to be splitting apart at the point, or the sharecracking off from the land-side bar, this point or cap completely binding and protecting it from further injury, as well as preventin g earth, grass, &c.,fro1;n being caught in the split and clogging the plow. (See the accompanying drawings.)

Figure 1 represents a perspective view of the lower portion of a plow with this point attached from the furrow side. Fig. 2 is an elevation of same landside. Fig. 3 is a perspective view of under side of same. Fig.4is a plan of a plow from which the point is worn away by use, and which is also cracking apart at d. Fig. 5 is a crosssection of the hollow point.

A is the share improved hollow point, and is held in its place by a screw or bolt, a. When the original'poiut of a plow is worn off, as shown in Fig. 4, or when the share is cracked off from the landside. as atd, this point is adjusted byfirst cutting away the edge of the share, in the form shown by dotted line 6, Fig. 4, and then drilling the screw-hole s. The pointis theuiirmly secured by the bolt 01-. Thus it not only restores the original form of point, but clasps and binds the weak and breaking parts together and covers the crack, so as to prevent the plow being clogged by earth, or weeds be ing caught in the crack.

Having thus described my invention, what I claim as new, and desire to secure by Let- HINRICK KNIPHALS.
